4)  Measured between pri. trace for socket-outlet and near metal chassis (back cover). 
5)  Measured between primary solder pin and embossed metal chassis (bottom). 
6)  Measured on Stand-by pcb from pri. trace to secondary trace. 
7)  Measured on TRANS pcb from pri. trace to secondary trace. 
8) Measured between 

internal primary part of the mains switch 

and near metal chassis (back cover).
